3 major N-linked sites and one O-linked site are identified: site-specific N-glycosylation at typical Asn-Xaa-Ser/Thr motifs are due to asparagine glycosylation at sequence positions 117, 184, and 448, glycosylation at each individual site is heterogeneous: Asn117 glycosylation site contains high-mannose structures, whereas Asn184 and Asn448 are modified by complex/hybrid oligosaccharide structures. 2 further glycosylation site are identified in low abundance: the major oligosaccharides modifying Asn142 are biantennary monosialo and asialo hybrid and mannose-5-type structures, the other glycosylation site is at Thr61, elongation of O-fucose to bi-, tri-, and tetrasaccharides at Thr61 is identified at levels of about 0.7% |
